Jesus Son of Mary, the divine motherhood at the heart of the faith

Mary’s motherhood: the unbreakable bond

The statement “Jesus son of Mary” (Mk 6:3) is the only occurrence in the Gospels in which Jesus is identified exclusively by His mother, without reference to an earthly father. This exegetical datum reveals, at the same time, the virginity of Joseph and the centrality of Mary in the human identity of the Son of God. Mariology is born from here, from an irreducible Christological rootedness: who Mary is depends on who Jesus is, and the question about Jesus leads inevitably to Mary.

Mk 6:3, “Is this not the Son of Mary?”

In the synagogue of Nazareth, the astonished crowd asks: “Is this not the carpenter, the son of Mary, the brother of James, Joses, Judas, and Simon?” (Mk 6:3). The absence of Joseph in this formulation is interpreted by commentators as an indication of his death before the public ministry. The genitive “son of Mary” (ho huios tês Marias) underscores a bond of exclusive belonging: Jesus belongs to Mary in a singular and total way. John Paul II notes in Redemptoris Mater that this bond is eternal, for the eternal Son assumed humanity from the womb of Mary forever.

Theotókos and the divine motherhood

The Council of Ephesus (431) dogmatically defined that Mary is Theotókos, Mother of God, precisely because Jesus is a single divine Person in two natures. Mary’s motherhood reaches not only the human nature of Jesus, but the Person of the Word. To say “Jesus son of Mary” is, therefore, implicitly to affirm the hypostatic incarnation: the Second Person of the Trinity was born of a woman (Gal 4:4). Nestorius, by separating the “Christ son of Mary” from the “God Logos,” was condemned because he broke this unity that is the heart of the Christian faith.

Lk 1:31, “You will conceive and bear a Son”

The angel’s announcement in Lk 1:31 places Mary at the center of salvation history: “You will conceive in your womb and bear a son, and you shall call Him Jesus.” The name Jesus (Iêsous, Hebrew Yehoshua, “YHWH saves”) immediately reveals the mission of the son of Mary. Lumen Gentium no. 53 summarizes: “The Virgin Mary… is hailed as a pre-eminent and singular member of the Church and as her type and outstanding model in faith and charity.” Mary’s motherhood is thus at once biological, theological, and ecclesiological.

Mary, the New Eve

Irenaeus of Lyons (2nd century) developed the Eve-Mary typology: as death entered through the disobedience of Eve, so Life entered through the obedience of Mary (Adversus Haereses III,22,4). Jesus, the son of Mary, is the new Adam who recapitulates in Himself all creation. The genesis of Jesus passes through Mary’s “yes,” the fiat of Lk 1:38. This active cooperation makes Mary not merely a passive receptacle, but a co-agent of the incarnation, in the sense that the Holy Spirit worked in her with her free consent.

Jn 19:26-27, “Behold your mother”

On Calvary, Jesus entrusts Mary to the beloved disciple with words that the tradition interprets as a universal mission: “Woman, behold your son… Behold your Mother” (Jn 19:26-27). Mary’s motherhood expands: from mother of Jesus she becomes mother of the faithful. The “son of Mary” who dies on the Cross hands over His mother to the nascent Church. Redemptoris Mater no. 23 comments that Mary “remains maternally present” in the mystery of the Church, prolonging in time her historical motherhood in relation to Jesus.
